Device and method for detecting faults in electronic systems

A system comprising:

• a remote unit;
• an electrical system comprising at least one electrical control unit electrically connected to a plurality of electrical components;
• and
• a fault detection device for detecting faults in the electrical system, said fault detection device comprising:
• a first measuring unit configured to receive, from said electrical control unit, a first error value indicative of a fault in a subset comprising at least two of said plurality of electrical components;
• a communication unit configured to provide information to a user interface;
• a second measuring unit configured to be electrically connected directly and simultaneously to each of said at least two of said plurality of electrical components in said subset during a measurement;
• and
• a processing unit connected to and configured to control said first measuring unit, said second measuring unit, and said communication unit,
• wherein said second measuring unit is configured to, based on said first error value indicative of a fault in said subset, determine an operational status of each of said electrical components in said subset of electrical components;
• and
• wherein, said communication unit is configured to provide, to said user interface, an indication of said operational status.

A method for detecting faults in an electrical system using a fault detection device, said electrical system comprising at least one electrical control unit electrically connected to a plurality of electrical components, said fault detection device comprising a first measuring unit, a second measuring unit, a communication unit, and a processing unit connected to and configured to control said first measuring unit, said second measuring unit, and said communication unit, and said method comprising the steps of:

• receiving, by said first measuring unit, from said electrical control unit, a first error value indicative of a fault in a subset comprising at least two of said plurality of electrical components;
• determining, by said second measuring unit, based on said first error value, an operational status of each of said electrical components in said subset of electrical components, the second measuring unit being configured to be electrically connected directly and simultaneously to each of said at least two of said plurality of electrical components in said subset during a measurement;
• and
• providing, by said communication unit, to an user interface, an indication of said operational status, the communication unit being configured to provide information to the user interface.
